Embodiment 1
[0024] Example 1 Indoor Toxicity Measurement
[0025] 1. Drug preparation
[0026] The selected medicaments are: 92.5% dipropacyclopyrene technical product, 3% piperrine enamide aqueous emulsion. When making the compound insecticidal composition, the mass ratios of piperine and dipropacyclopyrene are respectively selected as 1:1, 2:1, 4:1, 10:1, 20:1, 40:1, and 80 :1, 100:1. The single agent and compound insecticidal composition are diluted with acetone to be 10000mg / L mother liquor for later use, and each single agent and each group of compounded mixtures are respectively diluted to 5-7 concentration gradients.
[0027] 2. Processing method
[0028] Toxic effects of insecticides on aphids were determined by insect dipping method. Pick fresh young apple shoots with aphids from the field, remove excess aphids, keep healthy wingless adult aphids with basically the same size, immerse them in the liquid medicine for 5 seconds, take them out and dry them, and put them in a filt...

[0045] Example 2: Field control effect of the piperpinenamide·dipropyridine insecticidal composition on the apple yellow aphid
[0046] 1. Processing conditions
[0047] The treatment object is yellow aphid, and the test crop is apple tree, and the variety is red Fuji.
[0048]The treatment was carried out at the treatment site of the Yantai Academy of Agricultural Sciences in Shandong Province, where the apple yellow aphid occurred generally and evenly over the years; during the treatment period, the apple growth period was the fruit expansion period, and the cultivation conditions of all treatment plots (soil type, fertilization, growth stage, Plant row spacing, etc.) and plant growth are uniform, and consistent with the local cultivation measures.
[0049] 2. Processing flow
[0050] The treatment agent is a 5% piperamine-diproppyridine insecticidal composition compounded according to 4:1 by the Institute of Plant Protection, Yantai Academy of Agricultural Sciences, Shand...
Embodiment 3
[0064] Example 3: Field control effect of the piperpinenamide·dipropyridine insecticidal composition on the green leafhopper of tea
[0065] 1. Processing conditions
[0066] The object of treatment is the tea leafhopper, and the treatment is carried out in Longquan Town, Mouping District, Yantai City, Shandong Province. The tested tea variety is Pingyang Tezao, and the occurrence of the green leafhopper is generally uniform in the tested tea gardens. The cultivation conditions (soil type, fertilization, growth stage, row spacing, etc.) and plant growth of all treatment plots were uniform and consistent with local cultivation measures.
[0067] 2. Processing flow
[0068] The treatment medicament is the 22% piperrine · dipropacyclopyrene insecticidal composition compounded according to 10: 1 by the Plant Protection Institute of Yantai Academy of Agricultural Sciences, Shandong Province (containing 20% piperine and 2% dipropane Pyrethrin), the contrast agent is 5% dipropacy...
